Que. 1

If I ask a person about fixed line, what am I referring to?

1.

Router

2.

Bridge

3.

Phone

4.

Modem

5.

Cable

Solution

Answer: A landline telephone (also known as land line, land-line, main line, home phone, landline, fixed-line, and wireline) refers to a phone that uses a metal wire or fibre optic telephone line for transmission as distinguished from a mobile cellular line, which uses radio waves for transmission. A fixed phone line (a line that is not a mobile phone line) can be hard-wired or cordless and typically refers to the operation of wireless devices or systems in fixed locations such as homes. Fixed wireless devices usually derive their electrical power from the utility mains electricity, unlike mobile wireless or portable wireless, which tend to be battery-powered. Although mobile and portable systems can be used in fixed locations, efficiency and bandwidth are compromised compared with fixed systems. Mobile or portable, battery-powered wireless systems can be used as emergency backups for fixed systems in case of a power blackout or natural disaster.

Solution

Answer: To enable OSPFv3, you enable the protocol as with RIPng. The command string is ipv6 ospf <process-id> area <area-id>. Open Shortest Path First (OSPF) is a routing protocol for Internet Protocol (IP) networks. It uses a link state routing (LSR) algorithm and falls into the group of interior routing protocols, operating within a single autonomous system (AS). It is defined as OSPF Version 2 in RFC 2328 for IPv4. The updates for IPv6 are specified as OSPF Version 3 in RFC 5340 (2008).

Solution

Answer: RIPng uses the multicast IPv6 address of FF02::9. If you remember the multicast addresses for IPv4, the numbers at the end of each IPv6 address are the same. The Routing Information Protocol (RIP) is one of the oldest distance-vector routing protocols which employ the hop count as a routing metric. RIP prevents routing loops by implementing limit on the number of hops allowed in a path from source to destination. The maximum number of hops allowed for RIP is 15, which limits the size of networks that RIP can support. A hop count of 16 is considered an infinite distance and the route is considered unreachable. RIP implements the split horizon, route poisoning and holddown mechanisms to prevent incorrect routing information from being propagated.

Solution

Answer: Google Glass uses which OMAP (Open Multimedia Applications Platform). Google Glass is an optical head-mounted display designed in the shape of a pair of eyeglasses. It was developed by X (previously Google X) with the mission of producing a ubiquitous computer. Google Glass displayed information in a smartphone-like hands-free format. Wearers communicated with the Internet via natural language voice commands.Google started selling a prototype of Google Glass to qualified "Glass Explorers" in the US on April 15, 2013, for a limited period for $1,500, before it became available to the public on May 15, 2014. It also has a camera attached to it.

Solution

________ is a prtocol designed by Cisco for automating routing decisions and configuration.

1.

CEF

2.

EIGRP

3.

VMPS

4.

GLBP

5.

IGRP

Solution

Answer: Enhanced Interior Gateway Routing Protocol (EIGRP) is an advanced distance-vector routing protocol that is used on a computer network for automating routing decisions and configuration. EIGRP is used on a router to share routes with other routers within the same autonomous system. Unlike other well known routing protocols, such as RIP, EIGRP only sends incremental updates, reducing the workload on the router and the amount of data that needs to be transmitted.

Name the technique used for driving a multiplexed display in which relatively few I/O pins on a microcontroller are used to drive an array of LEDs.

1.

Open collector

2.

Johnson counter

3.

Charlieplexing

4.

Bit banging

5.

Wallace tree

Solution

Answer:

Charlieplexing is a technique for driving a multiplexed display in which relatively few I/O pins on a microcontroller are used to drive an array of LEDs. The method uses the tri-state logic capabilities of microcontrollers in order to gain efficiency over traditional multiplexing. Although it is more efficient in its use of I/O, there are issues that cause it to be more complicated to design and render it impractical for larger displays. These issues include duty cycle, current requirements and the forward voltages of the LEDs. Charlieplexing was proposed in early 1995 by Charlie Allen at Maxim Integrated. The method, however, was known and utilized by various parties much earlier in the 1980s, and has been described in detail as early as in 1979 in a patent by Christopher W. Malinowski, Heinz Rinderle, and Martin Siegle of Department of Research and Development, AEG-Telefunken, Heilbronn, Germany for what they called a "three-state signaling system".

Your router has the following IP address on Ethernet0: 172.16.2.1/23. Which of the following can be valid host IDs on the LAN interface attached to the router?
(a)172.16.1.100
(b)172.16.1.198
(c)172.16.2.255
(d)172.16.3.0

1.

a only

2.

b and c only

3.

c and d only

4.

a and d only

5.

None of the above

Solution

Answer: The router's IP address on the E0 interface is 172.16.2.1/23, which is 255.255.254.0. This makes the third octet a block size of 2. The router's interface is in the 2.0 subnet, and the broadcast address is 3.255 because the next subnet is 4.0. The valid host range is 2.1 through 3.254. The router is using the first valid host address in the range.
